The purpose of this thesis is to explore various harmonization scenarios for North Atlantic en route user charges. The current charging system involves eight countries, each with their own method for computing user charges. ...

Headcut retreat produced by plunge pools is represented using existing concepts about this type of erosion. The model estimates retreat rates, given flow, height of the headcut, upstream slope and Manning's roughness, and ...

Pure Home Water (PHW) is a social enterprise that promotes and disseminates household drinking water technologies in the Northern Region of Ghana. Currently their main product is a pot-shaped Potters for Peace-type ceramic ...

Over the past decades, scientists and engineers have tried to develop and improve various devices and control systems in order to mitigate and prevent civil structures against external dynamic forces such as strong wind ...

Pure Home Water (PHW) is a non-profit based in Ghana that seeks to bring safe drinking water to those most in need in Northern Ghana through the production, sale, and distribution of ceramic pot filters (CPF) and other ...

With an annual production of more than 20 billion tons a year, concrete continues to be the world's dominating manufacturing material for a foreseeable future. However, this ubiquity comes with a large ecological price as ...

The purpose of this study is to investigate the technical feasibility of high density polyethylene (HDPE) containers as an alternative to polyethylene terephthalate (PET) bottles for the solar disinfection of drinking water ...

Titanium has been used to meet ever-stricter standards for high-temperature performance, creep resistance, low weight and high strength. Having low density, a high melting point, and high tensile strength, it seems like ...

The fundamental challenge for the structural engineer in designing earthquake-resistant structures is to design buildings with both adequate ductility and sufficient stiffness. Traditional lateral force resisting systems ...

High-speed rail (HSR) is primarily for intermediate distance intercity passenger travel. The concept of high-speed rail commuting is to provide short distance commuting transportation service on dedicated HSR, by sharing ...
